How do I change the key of a YouTube song?

Could someone please send me the link where I put the YouTube song to convert it to a new key?

The [u]Change Pitch[/u] effect. (You don’t have to fill-in all of the boxes… You can enter the key notes, OR the number of half-steps, OR the frequencies, OR the percentage.)

Or if it’s a slight change and you can live with the associated slight tempo change, the Change Speed effect changes the speed and pitch together. It’s “simpler” and less prone to artifacts (other than the expected tempo change).
